Scientists from around the world have joined forces to lay the foundations for an experiment of truly astronomical proportions: putting together the biggest map of the Universe ever made. The experiment will combine signals from hundreds of radio dishes to make cosmic atlas.
On Christmas Day 2003, a kitchen table-size lander descended onto the surface of the red planet on a mission to study the Martian surface and potential clues for life. The probe never called home, and no one knew what happened to it. Until now.
The theory that an Anthropic Principle guided the physics and evolution of the universe was initially proposed by Brandon Carter; this theory was later debated by Cambridge scholar Stephen Hawking and a widening web of physicists around the world. German scholar Ulf-G Meissner adds to a series of discoveries that support this Anthropic Principle.
The catalogues of celestial objects contain a galaxy cluster called 'Abell 4067'. Recent observations with the XMM-Newton space observatory, however, reveal evidence that this object actually constitutes of the merger of two clusters. The smaller system appears to be losing the greater part of its gas.
Astronomers have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars - extremely luminous objects powered by supermassive black holes with the mass of a billion suns - regulate the formation of stars and the build-up of the most massive galaxies.
By analyzing the light of hundreds of thousands of celestial objects, astronomers from the Sloan Digital Sky Survey (SDSS) have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars.
